New Zealand allows dual citizenship or multiple citizenship — but some other countries don’t.
Check the other country's rules
You can have NZ citizenship and be a citizen of another country at the same time — unless the other country doesn't allow it.
Check what the other country's rules are:
When you apply for NZ citizenship
You need to say which countries you are already a citizen of.
If the other country allows dual citizenship, that's all you need to do.
If the other country does not allow dual citizenship, you need to give up citizenship of that country.
Dual citizenship if you have a baby in NZ
If you give birth in New Zealand and you or the other parent is an NZ citizen or permanent resident, your baby is automatically an NZ citizen.
If you're from a country that allows dual citizenship, you can also apply to the other country for citizenship for your child.
If you're from a country that doesn't allow dual citizenship, your baby might not be able to give up their New Zealand citizenship to become a citizen of your home country until they turn 18.
If you want your baby to hold citizenship for your home country instead of NZ, you might need to travel home to give birth.
If you have to give up NZ citizenship
You might have to give up your NZ citizenship if you want to become a citizen of a country that doesn’t allow dual citizenship.
